Abstract

|
A new technique was proposed for the determination of alkylphenols, chlorophenols and bisphenol A in tap water samples. The sample preparation consists of a solid phase extraction (SPE) of alkylphenols, chlorophenols and bisphenol A from a water sample with XAD-4 and subsequent conversion to isobutyloxycarbonyl (isoBOC) derivatives or tert-butyldimethylsilyl (TBDMS) derivatives for sensitive analysis with the CC/MS SIM mode. The recoveries were 86.6 ¡ 105.2£¥ (isoBOC derivatization) and 97.6¡484.5£¥ (TBDMS derivatization), respectively. The limit of quantitation of alkylphenols, chlorophenols and bisphenol h for SIM were 0.001¡0.050 /1 (isoBOC derivatization) and 0.003¡0.050 /1 (TBDMS derivatization). The SIM responses were linear with the correlation coefficient varying 0.9755¡0.9981 (isoBOC derivatization), and 0.9908¡0.9996 (TBDMS derivatization). When these methods were applied to tap water samples, the range of concentrations were 22.8¡31.3 ng/1 in 2,4-dichlorophenol, 28.6¡70.3 ng/1 in pentachlorophenol, 15.2¡17.4 ng/1 in t-butylphenol, 10.8¡13.2 ng/1 in t-octylphenol and 17.6¡36.3 ng/l in bisphenol A, respectively.
